Product Features
Brief Introduction
High-quality low-latency video footage
This product supports HD-SDI&3G-SDI input and output as well as HDMI full-HD
input and output, with the highest resolution of 1080P/60Hz. With the use of H.264
coding-decoding technology with high compression ratio and high definition, the
images have high definition, and the latency is as low as 70ms.
V-Mount battery, NP-F battery and non-line-of-sight transmission features
This product is designed based on 1.4Ghz wireless network technology. The lower
frequency makes it have better penetrating characteristics and can be transmitted
under non-line-of-sight conditions, and this frequency is not easy to be interfered
by the external environment.
Point-to-point mode and streaming mode
This product supports switching between two operating modes, namely point-to-
point mode and RTSP streaming mode. In point-to-point mode, the video output
interface is HDMI or SDI. In RTSP streaming mode, the video streaming interface
is RJ45 network interface. There are more options for different applications.

(7074A+3074A) wireless network technology for transmission. Image processing
is performed using H.264 coding-decoding technology, and thus the images are
clearer and the latency is lower.It can be widely used in live events, concerts,
sporting events, education, churches, etc.
